To all whGTItE/Z may concerm I Be it known that I, J OHN HENRY PHILLIPS, a citizen of the United States, residing the; city and county of Jackson, State'of Michigan, have invented certain new andnseful Improvements in Pipe or Hose Coupg s, of which the following is a specification,

This invention relates to improvements'in nine or hosecouphng.

ticnlarfly adapted and,'as shown in the accompanying drawing, 1s des gned for use as a coupling for the steam and'au' pipes of rail:

1 third, to provide an improved coupling for the pipes of railway trains in which a car l having a combination coupling may be read-" ily coupled or connected to 'a carequippedwith individual coupling; fourth, to provide in a coupling an Improved packing ring; and fifth, to provide an-improved'pipe or hose couplingwhich is very simple and'econominal in structure, very durable in use, and not likely to get out of repair.

-..Further objects, and objects relating to details of construction, will definitely appear from the detailed description'to follow.

v accomplish the objects of my invention' by the devices and means described in the -Wardlypr oject1ng conical latch having a' following specification.

The invent on 1s clearly -defined and pointed out in the claims;

A structure embodying the features of my inventionis clearly illustrated in the accom panying drawing, forming a part of this specification, in Wh1'ch:-

In the drawings, simi ar reference characters refer to similar parts throughout the severalviews. 'The sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

, Referring to the drawings, 11 represents the end sills or frame pieces of a pair of railway cars, 2 the draw heads and 3 the draw bars thereof. The pipes 4, 5 and 6 are the air signal, air brake and steam pipe,respe c tively, of the cars. Each set of pipes is provided with a coupling member comprising a head v7, having a plurality of bores 8 therein, into which the-pipes are preferably-threaded and which terminate on the, front faces of the heads in packing ring sockets or chambers. Each head is provided on one side with a fordownturned hook 11 at its forward end and .on the, other side with a corresponding conical socket 12 which'is open at its inner end, as at 13, to receive the hook 1 1 of thelatch, thus forming catches therefor, as clearly appears in Fig. 5. These conical latches and sockets effectively, guide the heads together; so that the packing rings are automatically support the parts by means of the hangers 14,

I which are preferably U-shaped in form and are provided with loops at their lower ends adapted to. embrace a plurality of the pipes I 5 to be coupled at the rear of the head. See

Fig. 3. These hangers are preferably formed I "and thejouter'bearing lip being adapted to of springmetal .rods', and the springcoils 16' are preferably formed therein, the coils being tapping into the-bottom of the same and securing by means ofthe set, screws 17. The.

'hangers are so arranged as to-hold the'heads normally in-a tilted position, suitable collars" as 18 being preferablyprovided to limit the These collars are adjustaby. secured on thepip'es by means: of

pipes 4. and 6. My improved flexible joint or coupling preferably consists of a socket member, comprising the flange 20 threaded upon one of the pipe sections-on which the cap 21 is threaded, the cap 21 being-provided with'an inwardly-projecting flange 22- having a flaring mouth 23. The socket is thus easily formed and-assembled. On the other pipe section is a flange-like swivel 24 adapted U-s'haped packing the arms of the packing ened portions or bearing hps 26-adapted to 5'5 engage the ends of the pipes. this. ar-

The rubber ac 'ing rings may be utilized if'desired in this relation,- as they are 120.

not injured by the heat, as would be the case it used for the. steam pipes 6. I In order that my improved coupling heads might be used in connection with the coup- I- prov tle what I lings now in common use, I designateas emergency heads 39, which are provided with coupling members 40 and 41 of-the type now quite generally in use, to which the regular coupling members may be attached, the head 29 being adapted to be ceases attached to one of my improved coupling members. fllhis coupling head 39 is prefer ably provider! with inwardhprojecting upturned hooks 42 adapted to lie-engaged under. the projections 43 on the coupling heads 7. On thetop of the coupling head 39 is "a pivoted latch aegadapted to engage the latch sockets 45 provided therefor in the head' See- Fig. 10.

The heads 39 are provided with the forwardly-proj ecting latch members and. sockets 10 and 12, adapted to coact with the corresponding latch members provided for the head 7, as described.

" To further adapt my combination couplings'for use in connection with my individual couplers as shown in Figs. 11, 12, and

13, r I provide the same with sockets 47 adapted to receive the latches 49 on the individ ual coupling member 48. These sock-' ets are arranged so that. the individual couplers are held in proper relation. are held int-he coupling heads preferably by the spring catches 50. See Fig. 11.

In Fig. 12 I illustrate a pair of individual couplings 48, which are provided with catches 51 adapted to be engaged by the latches 49 when properly brought end to end.

adapted to engage over the ends of the latches, as clearly appears from-the drawing, thus effectively retaining the'parts together byfpermitting their being disengaged by a rocking movement. thereof, in which the trated' and described, I secure a coupling which is adapted to be automatically en- I have illustrated and described the same count of its structural simplicity and economy.
